Abstract

The invention relates to the field of nickel electroplating, in particular to a bright black nickel plating electroplate solution and a preparation method and application thereof. The bright black nickel plating electroplate solution is prepared from the components with the following concentrations: 25-65g / L of a mixture of hexaimidazole nickel (II) carbonate pentahydrate (HINCPH) and chitosan nickel (II) (CTN) by equal mass, 15-45g / L of nickel sulfate, 10-35g / L of nickel chloride, 3.5-12.5g of iron sulfate, 3.5-12.5g of zinc sulfate, 3.5-12.5g of copper sulfate, 1.5-5.5g of magnesium sulfate, 1.5-5.5g of manganese sulfate, 0.5-3.5g of silver nitrate, 15-30g / L of thioacetamide, 20-55g / L of a stabilizer, 25-65g / L of a mixture, 15-35g / L of a mixing agent and 5-25g / L of black brightener. Thecompounding agent used by the prepared novel bright black nickel electroplating solution is mainly prepared from chitosan, chitosan oligosaccharide, imidazole, EDTA, thioamide and the like, the compounding agent can not only be treated without pollution and harmlessness, but also be recycled and reused efficiently, and economic and environmental benefits are good.

Description

technical field [0001] The invention relates to the field of nickel electroplating, in particular to a bright black nickel electroplating solution and its preparation method and application. Background technique [0002] Black and bright nickel coatings have excellent heat absorption, heat dissipation, extinction and decoration functions. As high-efficiency light-absorbing materials, they have multiple uses and are widely used in optical equipment, light-absorbing materials, aerospace and defense industries. Black nickel coating is also widely used in decoration and protective film, active solar thermal coating for absorbing infrared light and other fields. Black nickel plating is also widely used as a conductive coating in the electronics industry, as an energy absorption conversion coating in the field of solar energy, functional coatings, computing, petrochemicals, electronics, automobiles and other fields.
